Communication Mode Switching for Relay Station Signal Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile stations cannot determine whether relay stations are in an operational state, leading to high signal loss probability due to relay stations being in abnormal states or being too far away, resulting in unsuccessful signal transmission and poor user experience.
Innovation Solution
A communication mode switching method and device that detect radio frequency signal strength thresholds to switch between relay and offline modes, using the receiving frequency of the downlink channel for transmission when the relay station is in an abnormal state to ensure signal receipt by other mobile stations within coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the relay station operates in a mode of quickly activating the relay station, then the call admission time is greatly reduced, but the relay station is in an abnormal state when no signal is relayed, leading to high signal loss probability
Solution Approach 1:
The mobile station performs preliminary detection of downlink channel signal strength before initiating signal transmission. By detecting whether the signal strength meets a first threshold in advance, the mobile station can determine if the relay station is in an operating state before attempting transmission, thereby avoiding unnecessary transmission failures and improving signal transmission reliability while maintaining fast call admission.
2Device complexity
If the mobile station transmits signal in relay mode without detecting relay station state, then the transmission process is simple, but the transmitted signal cannot be received by other mobile stations, resulting in high loss probability
Solution Approach 1:
The mobile station uses downlink channel signal strength detection as a feedback mechanism to determine the relay station's operating state. This feedback information guides the mobile station to dynamically switch between relay mode and offline mode, ensuring that signals are transmitted in a manner that guarantees reception by other mobile stations while maintaining relatively simple transmission processes.
3Reliability
If the mobile station uses downlink channel receiving frequency for transmission in offline mode, then signal loss probability is reduced, but the transmission process becomes more complex
Solution Approach 1:
The mobile station implements dynamic communication mode switching between relay mode and offline mode based on real-time detection of downlink channel signal strength. This dynamic adaptation allows the system to automatically select the most appropriate transmission mode according to current conditions, improving signal transmission reliability while managing complexity through automated decision-making rather than manual configuration.

AI summary
The present invention discloses a communication mode switching method and device. The method comprises: receiving a sending request (S101); detecting whether the radio-frequency signal strength of a downlink channel meets a first threshold (S102); when the radio-frequency signal strength is greater than or equal to the first threshold, determining that a relay station is in a working state, and keeping a relaying mode to finish the sending request (S103); when the radio-frequency signal strength is less than the first threshold, determining that the relay station is in an abnormal state, and switching to an offline mode to finish the sending request (S104), the offline mode specifically being to perform sending after regulating the sending frequency to be the receiving frequency of the downlink channel. It can be seen that, whether the relay station is in the abnormal state is determined by detecting whether the signal strength of the downlink channel meets the preset threshold, and sequentially, the working mode is switched between the relaying mode and the offline mode in a targeted manner, so that when the relay station is in the abnormal state, the receiving frequency of the downlink channel is used as the sending frequency for sending signals, so as to ensure that other mobile stations are capable of receiving the sent signals, and the rate of call loss is lowered.
